												  Lichen BiologyThis page intentionally left blank Lichen Biology Lichens are symbiotic organisms in which fungi and algae and/or cyanobacteria form an intimate biological union. This diverse group is found in almost all terrestrial habitats from the tropics to polar regions. In this second edition, four completely new chapters cover recent developments in the study of these fascinating organisms, including lichen genetics and sexual reproduction, stress physiology and symbiosis, and the carbon economy and environmental role of lichens. The whole text has been fully updated, with chapters covering anato- mical, morphological and developmental aspects; the chemistry of the unique secondary metabolites produced by lichens and the contribution of these sub- stances to medicine and the pharmaceutical industry; patterns of lichen photosynthesis and respiration in relation to different environmental condi- tions; the role of lichens in nitrogen fixation and mineral cycling; geographical patterns exhibited by these widespread symbionts; and the use of lichens as indicators of air pollution. This is a valuable reference for both students and researchers interested in lichenology. T H O M A S H .

He has over 35 years teaching experience in Ecology, Lichenology and Statistics, and has taught in Austria (Fulbright Fellowship) and conducted research in Australia, Germany (junior and senior von Humbolt Foundation fellowships), Mexico and South America, and the USA.

We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) of Degelia plumbea was observed. We propose a revised generic classification for the Pannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as morphological and chemical data available.

												  An Evolving Phylogenetically Based Taxonomy of Lichens and Allied FungiOpuscula Philolichenum, 11: 4-10. 2012. *pdf available online 3January2012 via (http://sweetgum.nybg.org/philolichenum/) An evolving phylogenetically based taxonomy of lichens and allied fungi 1 BRENDAN P. HODKINSON ABSTRACT. – A taxonomic scheme for lichens and allied fungi that synthesizes scientific knowledge from a variety of sources is presented. The system put forth here is intended both (1) to provide a skeletal outline of the lichens and allied fungi that can be used as a provisional filing and databasing scheme by lichen herbarium/data managers and (2) to announce the online presence of an official taxonomy that will define the scope of the newly formed International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF). The online version of the taxonomy presented here will continue to evolve along with our understanding of the organisms. Additionally, the subfamily Fissurinoideae Rivas Plata, Lücking and Lumbsch is elevated to the rank of family as Fissurinaceae. KEYWORDS. – higher-level taxonomy, lichen-forming fungi, lichenized fungi, phylogeny INTRODUCTION Traditionally, lichen herbaria have been arranged alphabetically, a scheme that stands in stark contrast to the phylogenetic scheme used by nearly all vascular plant herbaria. The justification typically given for this practice is that lichen taxonomy is too unstable to establish a reasonable system of classification. However, recent leaps forward in our understanding of the higher-level classification of fungi, driven primarily by the NSF-funded Assembling the Fungal Tree of Life (AFToL) project (Lutzoni et al. 2004), have caused the taxonomy of lichen-forming and allied fungi to increase significantly in stability. This is especially true within the class Lecanoromycetes, the main group of lichen-forming fungi (Miadlikowska et al.

												  Peter D. Crittenden: Meta-Analysis of an Exceptional Two-Decade Tenure As Senior Editor of the Lichenologist, the Flagship Journal of LichenologyThe Lichenologist (2021), 53,3–19 doi:10.1017/S0024282920000560 Review Peter D. Crittenden: meta-analysis of an exceptional two-decade tenure as senior editor of The Lichenologist, the flagship journal of lichenology Robert Lücking Botanischer Garten und Botanisches Museum, Freie Universität Berlin, Königin-Luise-Straße 6–8, 14195 Berlin, Germany Abstract Peter D. Crittenden served as senior editor of The Lichenologist, the flagship journal in the field of lichenological research, for a period of two decades, between 2000 and 2019. A review of the development of the journal and the publication output during this period is provided. The number of papers published during this period (1197) matches that of all papers published under the three previous senior editors, Peter W. James, David L. Hawksworth and Dennis H. Brown, during a much longer period of 42 years from 1958 to 1999. Peter oversaw important editorial changes to the layout and content of the journal: an increased size with a modern cover design, leaving behind the classic mint-coloured cover of more than 40 years; the addition of ‘thematic issues’ and encouragement of large monographs; implementation of substantial changes to the Code, such as effective electronic publication and obligate registration of new fungal names; and more recently a new policy to reject so-called ‘single naked species descriptions’. Shortly before Peter took over as senior editor, The Lichenologist had received its first impact factor, and Peter managed to continuously increase this measure from around 0.9 to lately up to over 1.5, higher than most other competing journals. The 1197 papers between 2000 and 2019 were published by a total of 1138 different authors, more than half of whom appeared just once as author, whereas a small number participated in numerous (up to 93) papers.
